Liquid-crystalline bisadducts of [60]fullerene
(Amer Chemical Soc, Washington, 2006)
A second-generation cyanobiphenyl-based dendrimer was used as a liquid-crystalline promoter to synthesize mesomorphic bisadducts of [60]fullerene. Liquid-crystalline trans-2, trans-3, and equatorial bisadducts were obtained ...
Ring closing metathesis/fragmentation route to (Z)-configured medium ring cycloalkenes. Total synthesis of (+/-)-periplanone C
(Amer Chemical Soc, Washington, 2006)
The combination of ring closing metathesis and beta-fragmentation offers an efficient entry into (Z)-configured medium ring cycloalkenes. The fragmentation step can be effected under anionic or radical conditions. The ...
